Claims.

This invention relates to certain new and useful improvements in nursingbattles for infant feeding.

One of the objects of the invention is to provide a nursing unit of thischaracter having novel means for simply and effectually venting thebottle during feeding, the means being so designed as to enableadjustment of the vent or vents within certain predetermined limits.

Another object is to provide a nursing bottle using a screw cap todetachably retain the nipple on the bottle and forming in that portionof the nipple confined between the cap and the bottle one or more ventpassages defined by structure wholly built into the nipple.

Other features of the invention reside in the construction andarrangement of parts hereinfragmentary cross section thereof taken online.

2-2, Figure 1. Figure 3 is an enlarged top plan view of the nipple.Figure 4 is an enlarged bottom plan view thereof.

Similar characters of reference indicate corresponding parts throughoutthe several views.

The invention has been shown in connection with the wide-mouthed type offood cell or nursing bottle Ill having thread-forming ribs II at itsopen end with which a, detachable screw cap or ring-shaped cover I! isengageable for removably clamping the nipple iii in place on the bottle.This nipple is provided at its lower end with an outwardly-facingannular attaching flange H which is adapted to engage the top edge ofthe bottle and be clamped thereto by the screw cap. To effectually guardagainst the infantspulling the nipple from its clamped position, theopposing contiguous faces of the cap and the nip le-flange are providedwith an inter-engaging annular tongue i5 and groove l6, respectively. Itwill be noted that the bulbous or breast portion of the nipple projectsthrough the opening H in the cap with the lower or base portion thereofin surface contact with the edge of such opening, and, as shown inFigure 2, the periphery of the base flange of the nipple fits snugly atits periphery against the inner wall of the cap.

For the purpose of venting the bottle during nursing and assuring thefree withdrawal of its contents by the infant as well as preventing col-'2 lapse of the nipple during feeding, I provide capillary-like ventchannels between the nipplefiange: I4 and the contiguous portion of thecap and bottle. By preference, this vent structure is provided for inthe construction of the nipple itself and to that end consists of one ormore pairs of relatively narrow spaced ribs'l8, l9 defining ventchannels disposed substantially radially on the top and bottom faces ofthe nipple-flange in the same registering plane and extending part wayat their inner ends along the adjoining outer and. inner faces of thebulbous portion of the nipple. In its periphery the nipple-flange hasnotches or recesses 20 therein which span or bridge the space defined bythe companion pairs of ribs and form a connecting channel between theouter ends of the rib-forming channels. The bottom or bottle-engagingface of the. nipple flange has arcuate ribs 2| arranged between and ofthe same height as the radial ribs l8, IQ for the purpose of providinga, continuous and even bearing between the nipple and the bottle. Bythis construction, in the assembled position of the parts for feeding,the interior of the bottle is in vented communication with theatmosphere, the ribs l8, l9 and notches 20 forming with the contiguousportions of the cap and the bottle an uninterrupted capillary channelfor effectually venting the bottle during feeding.

By screwing the cap l2 home with varying degrees of pressure to compressthe ribs l8, l9 within certain limits, the capillary rib-forming, ventchannel may be governed as to size and thereby enable the channel to bereadily regulated as desired. For this purpose and to facilitate suchregulation, the cap is provided on its side-wall with an indicator ormark 22 and the adjoining portion of the bottle is provided withcomplemental spaced indicators or marks 23, 24 which represent theminimum and maximum positions to which the cap is screwed home to inturn govern the corresponding maximum and minimum sizes to which thevent channel may be regulated. When the cap is screwed to a'positionwhere its indicator registers with the bottle indicator 23 the maximumsize of the vent channel is obtained and when such cap-indicatorregisters with the bottle-indicator 24 the minimum size of vent channelis provided. These indicators may be in the form of colored lines or ofany other'appropriate character.

I claim as my invention:

1. A nursing unit, comprising a bottle having a a cap detachably mountedthereon containing an opening centrally thereof, and a nipple adapt- 3ed to be mounted on the bottle and to extend through said cap-opening inclamping relation to the cap and having a base-flange for dispositionbetween the top edge of the bottle and the underside of the top marginalportion of the cap about its openingsaid nipple-flange having ventpassages formed in its' top. and bottom faces with.

the bottom passage opening into the bottle and the top passage openinginto the atmosphere between the cap and the nipple.

2. A nursing unit, comprising a bottle having a cap detachably mountedthereon containing an opening centrally thereof, and a nipple adapted tobe mounted on the bottle and to extend through said cap-opening inclamping relation to the cap and having a base-flange for dispositionbetween the top edge of the bottle and the underside of the top marginalportion of the cap about its opening, said nipple-flange having alining,intercommunicating pairs of ribs in the top and bottom faces thereof andthe adjoining portion of the nipple having similarribs along its outersurface to form with the contiguous underside of the cap-top and the topof the bottle, respectively, a vent channel opening at one end into thebottle and at'its other end between the cap and the nipple into theatmosphere.

3. A nursing unit, comprising a bottle having a cap detachably mountedthereon containing an opening centrally thereof, and a nipple adapted tobe mounted on the bottle and to extend through said cap-opening inclamping relation to the cap and having a base-flange for dispositionbetween the top edge of the bottle and the underside of the top marginalportion of the cap about its opening, said nipple-flange having aliningpairs of spaced ribs in the top and bottom faces thereof extendinginwardly from the periphery of such flange and the adjoining portion ofthe nipple having similar ribs along its outer surface to provide ventchannels between the opposite faces of said flange and the cap andbottle and between the cap and the nipple, the bottom channel opening atits inner end between the nipple and the edge of the cap-opening, theperiphery of the nipple-flange having a notch formed therein bridgingthe space between said top and bottom ribs and forming a connectingchannel between the outer ends of the rib-forming channels.

4. A nursing unit, comprising a bottle having a screw cap detachablymounted thereon containing an opening centrally thereof, and a nippleadapted to be mounted on the bottle and to extend through saidcap-opening in clamping relation to'the cap and having a base-flange fordisposition between the top edge of the bottle and the top marginalportion of the cap about its opening, said nipple flange having spacedribs formed thereon for facial contact with the underside of the cap andthe top edge of the bottle when the cap is screwed down intonipple-retaining position and the adjoining portion of the nipple havingsimilar ribs along its outer surface to provide a vent channel openingat one end into the bottle and at its other end to the atmospherebetween the nipple and the edge of the cap-opening, the size of the ventchannel being Number variable by screwing the cap down more or lessbeyond its normal cap-retaining position to compress the ribs and reducethe size of the channel.

5. A nursing unit, comprising a bottle having a screw cap detachablymounted thereon containlng an opening centrally thereof, and a nippleadapted to be mounted on the bottle and to extend through saidcap-opening in clamping relation to the cap and having a base flange fordisposition between the top edge of the bottle and the top marginalportion of the cap about its opening; said nipple flange having spacedribs formed thereon for facial contact with the underside of the cap andthe top edge of the bottle when the cap is screwed down intonipple-retaining position and the adjoining portion of the nipple.having similar ribs along its outer surface to provide a vent channelopening at one end into the bottle and at its other end to theatmosphere between the nipple and the edge of the cap-opening, the sizeof the vent channel being variable by screwing the cap down more or lessbeyond its normal cap-retaining position to compress the ribs andjreducethe size of the channel, the bottle and cap having complementary marksthereon for indicating to the user the normal position of the parts formaximum venting and for minimum venting.
